In the logs (for internal reference by CSEs):

The following message is for ZEDEDA Technical Support staff to verify that you are experiencing the error described here, rather than something else.

Controller certificate ID was not found for the corresponding context:

lookupControllerCert(7306a9f1ec614f390a496e9ff3a7402a) not found

Decryption is unsuccessful:

da02830a-4b27-4dad-b5b7-97665480b52e, datastore config cipherblock decryption 
unsuccessful, falling back to cleartext: Controller Certificate get fail

Cause

This problem is known to impact version prior to 9.4.15. It happens when a node running one of the affected EVE versions tries to retrieve certificates from its controller over a weak internet connection.

Solution

Power cycle the device several times to ensure that EVE successfully retrieves the certificate from the controller.

If you continue to receive the same 400 response after power cycling your device, reach out to ZEDEDA Technical Support for further help.
